ONSD as an ICP Marker in vNOTES and TLH

Patients undergoing conventional total laparoscopic hysterectomy (TLH) are typically placed in the Trendelenburg position with intraabdominal carbon dioxide (CO₂) insufflation. These factors may contribute to intraoperative complications such as lymphedema, impaired pulmonary function, and increased intracranial pressure. Vaginal Natural Orifice Transluminal Endoscopic Surgery (vNOTES), a novel minimally invasive technique, provides retroperitoneal or transperitoneal access through the vaginal route and offers the potential for shorter operative times and lower intraabdominal pressure requirements. This study aims to evaluate whether the vNOTES technique can reduce intraoperative and postoperative complications compared with TLH. Particular attention will be given to hemodynamic parameters and changes in optic nerve sheath diameter as an indirect indicator of intracranial pressure.
